Monticello still uses the old class definition

Bug description

see MCClassDefinition >> fullDefinitionString

I'm sharing this here for reference. I started to work on this, but many MC tests began to fail once these changes were made. What is strange is that Monticello Mock classes (all classes in `MonticelloMocks) were deleted while running the Monticello tests with the following changes:

MCClassDefinition>>printDefinitionOn: stream
	stream nextPutAll: (
		self actualClass
			ifNotNil: [ : c | (ClassDefinitionPrinter for: c) definitionString ]
			ifNil: [ 'Class definition not found' ])

MCClassDefinition>>printClassDefinitionOn: stream
	"Print a class-side definition of the receiver on the given stream.
	Class instance variables and class traits."

	stream nextPutAll: (ClassDefinitionPrinter for: self actualClass class) definitionString.

MCClassDefinitionTest>>testDefinitionString
	| d |
	d := self mockClassA asClassDefinition.
	self assert: d definitionString equals: self mockClassA definitionString.
